Hi David,
What is passed is passed by value, thats right.
But for objects (instances of classes) the reference to the object is passed
so by using that reference you are able to manipulate the object.
What you can't modify to the outside are build-in (primitive) types like int
or boolean.
Here the values themselfs are passed by value and so .. you know.
If you would like to manipulate "simople" vaule you have to use
the wrapper classes of these primitve types (Integer or Boolean)

Regards
Michael
